The IEA said it expected UK emissions to fall again this year due to rising wind investment and the continued phase-out of coal.
The Government is under pressure to tackle a cost of living crisis that will see millions of UK households pay more than £2,000 in energy bills this year.
Despite growing investment in renewable energy, primarily wind, Britain is still reliant on gas for around 40 per cent of its electricity supply.
European gas supplies strained
More than half of this comes from Europe, where supplies have been constrained due to rising global demand, a long cold winter last year, disruption caused by Covid-19 and lower exports from Russia.
This has led to a rise in prices, leading to calls for green levies currently added to energy bills to be moved into general taxation to ease the cost of living pressure.
The Government has previously suggested it planned to move the bulk of levies from electricity bills onto gas bills to make running eco-friendly heat pumps and electric cars less expensive.
On Thursday, the Institute for Government, a leading think tank, warned that momentum around the Cop26 climate conference would “fizzle out” unless the Government urgently tackled the cost of living crisis.
Fatih Birol, the IEA’s executive director, said globally high electricity prices “risk becoming a driver of social and political tensions”.
He added: “Policy makers should be taking action now to soften the impacts on the most vulnerable and to address the underlying causes.
“Higher investment in low-carbon energy technologies including renewables, energy efficiency and nuclear power – alongside an expansion of robust and smart electricity grids – can help us get out of today’s difficulties.”
